HORSBESHOE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 325,054, dated August 25,1885.

Application filed December 20, 1854.

T0 aZZ whom it may concern:

Be it known that I, JOHN N. CLARKE, Jr., a citizen of the United States, and residing at Cincinnati, in the county ofHamilton and State of Ohio, have invented certain new and useful Improvements in Horseshoe Machines, of which the following is a specification.

My invention relates to improvements in machinery for making horseshoes, or more especially to the dies used for bending, shaping, and punching the shoe, all of which will be fully hereinafter described.

In the accompanying drawings, Figure l is a plan view of the operative parts of my invention claimed herein, showing the die and rollers employed in bending a blank bar into shape, a blank bar being shown in dotted lines in position preparatory to bending. Fig. 2 is a longitudinal vertical section on line as :r, Fig. 1. Fig.3 represents broken side elevations of the punches used in making the nail-holes. Fig. 4 is a longitudinal elevation of one form of blank bar that my machine is preferably designed to shape. Fig. 5 is a plan of the blank bar shown in Fig. 4. Fig. 6 is a detail perspective view of a detachable die-stock and one form of die used solely for bending the blank bar. Fig. 7 is a plan of the die shown in Fig. 6. Fig. 8 is a plan of a die used for both bending and otherwise shaping the shoe, showing a series of punches therein for mak ing the nail-holes. Fig. 9 is a longitudinal sectional elevation of the die shown in Fig. 8, taken on mixed line 3 y thereof. Fig. 10 is a central longitudinal section of the die shown in Figs. 8 and 9 without the punches.

A represents the base or bed-plate of the machine, having supports a a, and provided with the longitudinal irregular slots or ways A at either side its center.

B represents a reciprocating carriage or frame, suitably mounted so as to slide upon the bed-plate A.

B B are pitmen connecting with the frame 13 by means of the wrist-pins I) b, projecting laterally therefrom. These pitmen are shown broken off in Fig. 1; but it is clear without further illustration that they may be connected. with a crankshaft or other driving mechanism for operating the bending-frame B.

G 0 represent slotted transverse bars, being parts of the frame B, and having the bendingrollers c c suspended beneath the upper bar, 0, as shown in Fig. 2.

0 represents rollers surmounting the bending-rollers c c.

D D represent slides moving laterally in the slots of the transverse bars 0 G.

d d are bolts passing downwardly through slides D D, and the rollers c c 0 serving as journals for said rollers and securing the adjoining parts together. The bending-rollers 00 travel in the ways A in the movements of carriage B, and are thereby guided to properly bend the blank bar into shape. The rollers a being of greater diameter than the adjoining bending-rollers they pass freely along the upper face of the blank bar, and at the same time prevent any upward movement or buckling of said bar during the bending operation.

E represents a roller, journaled at its ends in boxes upon the carriage B, and provided with pinions e e, which are keyed thereon and engage rack-teeth c e on the upper face of the bed-plate to revolve said roller at the requisite time, as hereinafter specified.

F represents a squeezing-die, constructed on or attached to the periphery of roller E intermediate its ends, and having the same shape as the shoe to be made.

G represents the die around which the blank bar is bent. In Figs. 1 and 2it is shown projecting upward from v its base-plate g, which fits a cavity in the face of bed-plate A between the curved portions of the ways or slots A. Base-plate g of die G is detachably secured in place by the bolts 9.

G represents a shouldered edge or flange along the sides of the die, for receiving the inner shouldered edge of the blank, and H H are wings projecting laterally from said die to provide a bearing above the plane of the baseplate for that part of the blank bar that lies between the toe and heel calks. The opening h at the front of the die between said wings is provided to receive the toe-calks of the bar.

The wings H are cut away at their rear ends, forming shoulders h, which permit the heelcalks of the blank to pass inwardly toward the die without interruption in the bending operation.

In Fig. 6 I have shown the bending-die G so mounted upon its base-plate 9 that it can be adjusted thereon, and thereby adapt it to any possible variations or inaccuracies in the construction or movements of the bendingcarriage B. This manner of mounting the bending-die is a convenient one, as dies of different configurations can be readily exchanged one for the other, making it necessary for but one die-base, g, to be used. The bottom of the die is supplied with a dovetail tongue, I, which fits a corresponding groove, I, in the face of the base-plate. A slot, i, is cut in said base through which the bolts '5 pass for securing the die in the desired place.

In Fig. 8 I have shown a die that is adapted for bending and otherwise shaping and finishing the shoe; but I preferits use in connection with the roller-die F (shown in Figs. 1 and2) and the male drop-die (shown in Fig. 8) after the blank bar has been bent.

The die-stock or base-plate is recessed at M to receive the bent blank bar on m being cavities for containing the toe and heel calks thereof.

1 2 3 4 represent upright punches, arranged in series and suitably set in the channel M at either side the toe-cavity m, for making the nail-holes in the shoe.

The operation of punching the bent blank bar is performed by the squeezing-roller die F, which immediately follows the bending operation,when the die shown in Fig. 8 is placed in position on the bed-plate. The squeezingdie F-acts upon the blank when the pinions e e on roller E engage the racks e on the bedplate A. The outer and inner faces of the points of the punches 1 2 3 4 are constructed at varying angles, as shown in Fig. 3, so as to punch the nail holes correspondingly, and thereby make provision for the varying angles in the shape of the animals hoof.

The use of the double set of punches, one at either side the toe-calk, with their points constructed as shown, is an important feature of my invention, as all the nail-holes can be punched simultaneously and uniformly. It is obvious that instead of arranging said punches in the die itself they could be mounted in line in a head and used to punch the blank bar previous to bending it. The latter mode of mounting the punches would be preferable, because their points could be kept cool more readily by small jets of water than they could be in the shapingdies, as the blank bar is heated for operation in my machine.

hen the die shown in Fig. 8 is used as a bending-die prior to punching or otherwise finishing the blank bar therein, the rear face of the base-plate is constructed at a lower plane than the body thereof, leaving the shoulders h like unto the shoulders h on the dieplate shown in Fig. 1, both in form and purpose.

In Figs. 4 and 5 I show a blank bar adapted for use in the dies shown and described herein; but it is obvious that a plain bar, without the openings or spaces between the toe and heel ealks, or any bar used for making horseshoes, could be operated upon with but little alteration in the construction of the dies and without departing from the principle of my invention herein specified. If a plain blank bar should be used, the squeezing-die F would press itinto the recessed die shown in Fig. 8 and thereby form the nail-holes, creases, and toe and heel calks thereon.

I claim 1. In a horseshoe-machine, the combination, with a stationary base plate, A, having the irregular slots or ways A A, the die G, mounted thereon intermediate the slots A, and the rackteeth 6 e, of a-reciprocating carriage, B, provided with slotted transverse bars 0 O, bending-rollers c 0 c, suspended. from and operating laterally in the slots of said bars 0 C by means of said ways A, and the roller E, having pinions e e, and squeezing-die F, all constructed and adapted to operate substantially as herein set forth.

2. The combination, with the shaping-die G, having recess or channel M and calk-cavities mm, of the dotters or punchers 1 2 34, arranged and adapted to operate in connection with a squeezing-die, F, substantially as and for the purpose specified.

3. In a horseshoe-machine, the dotters or punchers 1 2 3 4, having their respective points constructed at varying angles to form simultaneously and uniformly the nail-holes in the shoe to suit the varying angles in the shape of the horses hoof, substantially as herein set forth.

In testimony of which invention I hereunto set my hand.
